Product Description
Redundant Power Supply Module Mitsubishi Universal model AJ35PTF-28DR
AJ35PTF-28DR Description
The AJ35PTF-28DR is an integrated compact remote digital input and output module designed for industrial fieldbus distributed control systems. It integrates built-in DC digital input channels and relay output channels in one compact unit, collecting switching signals from on-site sensors and switches while providing dry contact relay output to control solenoid valves, contactors, indicator lights and various industrial actuators. Supporting standard industrial fieldbus communication, it enables decentralized I/O deployment, simplifies on-site wiring, and delivers stable and reliable operation for automated production lines and machinery control systems.
AJ35PTF-28DR Key Features
